That's gotta hurt - BOD suffers nasty mouth injury at training

Leinster and Ireland star Brian O'Driscoll suffered a nasty mouth injury at training yesterday.

Taking to Twitter to showcase the unfortunate accident, the player showed us all why wearing gumshields is so important.

BOD tweeted a picture of a sore looking gash on his tongue, saying "*CAUTION* : the message of the day is always wear your gumshield training!"

It will take more than that to stop O'Driscoll, however, who is due to line out against Italy on Saturday. It will be his last ever home game for Ireland.

Once he steps out onto the field, the Leinster centre will become the most capped international of all time.
